Mod description
A simple quality of life mod that allows you to easily compare currently equipped items to those in your inventory with a keybind. Useful for comparing high-level equipment and curios when it's not immediately obvious which is better.

Why would you like the mod added?
Full disclosure, I wrote the mod and I find it to be a valuable addition to large modpacks like Enigmatica. It is highly compatible and doesn't detract at all for players that don't need to use it.

Screenshots if applicable.

I'll give it a try, thanks for the suggestion :)
